There are 9 kinds of welding technology for welded steel pipe 1. High-frequency resistance welding using the skin effect and proximity effect of high-frequency current, the edge of the billet steel strip is rapidly heated to reach the melting state, and the metal is extruded and fused under the action of extrusion roller to realize the welding method.
2. A submerged arc welding method for welding an arc under the cover of a flux. The weld pool solidifies into a weld under the protection of the flux coating, and the flux layer cools to cover the outer surface of the weld with slag shell.
3.Tungsten inert gas welding (TIG).Tungsten arc inert gas welding (TIG welding) is formed by inert gas welding of pure tungsten or activated tungsten (thorium tungsten, cerium tungsten, etc.) as the electrode. It is a welding method in which the base metal and filler wire are melted by the arc generated between the tungsten electrode and the welding piece under the protection of inert gas.
4. GMAWInert gas shielded welding using welding wire as the melting electrode.
CO2 shielded weldingFGCP welding with > 99.8% CO2 as shielding gas.
6. Hybrid gas shielded weldingGas shielded welding in which a mixture of two or more gases in a certain proportion is used as a shielding gas. Argon arc welding: gas shielded welding using argon as a shielding gas.
Pulse argon arc welding in which a base current is used to maintain the ionization channel of the main arc and a pulse current is periodically added to produce a pulse arc with a peak polarity pulse current to melt metal and control droplet transition.
8. Plasma arc welding method of welding plasma arc with high energy density is obtained by means of the binding action of the water-cooled nozzle on the arc.
9. Heat soldering the welding process, the metal material lower than the melting point of the base metal is used as the solder. The solder and the solder are heated to a temperature higher than the melting point of the base metal and lower than the melting point of the base metal. Induction brazing is the commonly used method for brazing composite steel.
